2.5kW - 48V Charger for Industrial Light Electric Vehicles based on STMicroelectronics Solution

The STDES-2KW5CH48V reference design offers a charging solution mainly for industrial light electric vehicles (LEVs), such as e-scooters, e-bikes, e-rickshaws, forklifts, micro e-cars. It is also suitable for AGV robots and power tools. The charger implements two charging profiles: one for Li-ion batteries and the other one for lead-acid batteries, corresponding to the latest trends of battery charging. The charger design is based on a boost power factor correction (PFC) circuit, controlled by the L4984D that provides high PF of greater than 0.9, followed by a DC-DC circuit based on a full-bridge LLC resonant power converter, controlled by the L6599A. For the output rectification, diodes have been chosen with an LLC transformer secondary winding using the center tapped configuration.
